Dom / Rick Dom — Complete Guide Across All Gundam Series

What Is the Dom? — From “Walking” to “Gliding”: The MS That Changed Ground Warfare

In the One Year War, mobile suits walked. While Zakus marched across battlefields at 88 km/h, one prototype shattered that paradigm entirely. 381 km/h — an 81-ton armored giant gliding across the earth on thermonuclear jet hover thrust. That machine was the Dom (MS-09).

But the Dom’s story is more than a technological breakthrough. This was the machine of Gundam’s most famous team: the Black Tri-Stars — Gaia, Ortega, and Mash. Three Doms in single-file formation, appearing as one blip on radar, charging in for the devastating Jet Stream Attack — a maneuver that remains part of anime’s shared vocabulary over 45 years later.

And the Dom carries another legend. An awakening Newtype named Amuro Ray destroyed 12 Rick Doms in under three minutes — a scene so shocking that the phrase became a permanent fixture in Japanese internet culture as shorthand for “overwhelming dominance.”

Born from Zimmad Company’s fierce rivalry with Zeonic, the Dom was converted into the space-use Rick Dom (MS-09R) and became Zeon’s primary space MS in the war’s final phase. Its lineage continued through 0080, 0083, ZZ, UC, and Thunderbolt, before being reborn in 2025’s GQuuuuuuX with a tripod high-mobility transformation.

MS-09 Dom — Specifications

Field	Detail
Model Number	MS-09
Classification	Ground Combat Heavy Mobile Suit
Height	18.6m
Empty Weight	62.6t
Max Weight	81.8t
Power Output	1,269kW
Thruster Thrust	58,200kg
Top Speed (Ground Hover)	381 km/h (prototype record)
Armor	Super-Hard Steel Alloy
Developer	Zimmad Company
Designer	Kunio Okawara

The Dom isn’t called a “heavy MS” just because it looks imposing. At 81.8 tons fully loaded, it weighs roughly 1.4 times as much as a Zaku II (58.1t). Yet its ground speed is over four times faster — a contradiction resolved through engineering brilliance.

The secret lies in the thermonuclear jet hover system built into the legs and waist skirt armor. High-temperature jets create an air cushion between the machine and the ground, levitating 81 tons of armored giant into a glide. The skirt armor isn’t just protection — it functions as airflow baffles that control the hover cushion while simultaneously shielding the delicate thrusters in the legs.

MS-09R Rick Dom — Space Variant

Field	Detail
Model Number	MS-09R
Height	18.6m
Empty Weight	43.8t
Max Weight	78.6t
Power Output	1,199kW
Thruster Thrust	53,000kg
180° Turn Time	2.1 seconds

The space combat variant replaces the ground hover jets with rocket thrusters. The 30% weight reduction (from 62.6t to 43.8t) reflects the removal of components only needed for gravity-bound operations.

When Gelgoog production couldn’t keep pace with demand in the war’s final months, the Rick Dom served as Zeon’s de facto primary space MS, holding the frontline through the final defense of A Baoa Qu.

Weapons

Weapon	Detail
360mm Giant Bazooka	10-round magazine. The largest MS-portable weapon of its era
Heat Saber	Superheated blade that melts through enemy armor
Spread Beam Gun	Chest-mounted. Disperses beam energy over wide area for blinding
880mm Rocket Bazooka	Optional loadout. 5-round clip

The Giant Bazooka — “One Shot, One Cruiser”

The weapon that defines the Dom is the shoulder-mounted 360mm Giant Bazooka. For perspective: a modern tank’s main gun is 120mm. The Giant Bazooka’s shells are three times that diameter, carrying enough destructive force to sink cruiser-class warships in a single hit. Before beam weapons became widespread, this was Zeon’s most devastating anti-ship weapon.

Zimmad’s bazooka technology was later inherited by Anaheim Electronics — the lineage traces all the way to the GP02A’s Atomic Bazooka in 0083.

The Spread Beam — An Underrated Built-In Weapon

The chest-mounted spread beam is often dismissed as “just for blinding,” but in the visual-range combat forced by Minovsky particles, disrupting an enemy’s vision is devastating. A Dom charges at full hover speed, fires a blinding flash from its chest, and closes with the Heat Saber before the target can recover — this is the Dom’s fundamental combat doctrine.

The Black Tri-Stars — “Heroes of Loum”

Team Profile

Field	Detail
Unit	Zeon Assault Mobile Force, 7th Division, Special Operations Team
Nickname	Black Tri-Stars
MS History	Zaku I → High Mobility Zaku II → Dom
Greatest Achievement	Capturing General Revil at the Battle of Loum

Captain Gaia — The Tactician

The brain of the Black Tri-Stars. Cool, calculating, and the inventor of the Jet Stream Attack itself. At the Battle of Loum, Gaia’s tactical brilliance crippled the Federation flagship Ananke and led to General Revil’s capture — a feat that earned the team the title “Heroes of Loum.”

But after losing Mash in Episode 24, Gaia’s famous composure cracked. In Episode 25, “The Battle of Odessa” (U.C. 0079, November 9), grief drove Gaia to recklessness. He charged Amuro’s Gundam seeking revenge for Mash — and fell to a pilot who had grown far beyond the boy they’d first encountered. The tactician destroyed by his own emotions — that irony gives Gaia’s final moments their particular tragedy.

Lieutenant Ortega — The Finisher

The last man in the Jet Stream Attack formation — the one who delivers the killing blow. A hulking close-combat specialist, fiercely loyal to his teammates yet harboring a quiet rivalry with Char Aznable.

What Ortega did in Episode 24 is seared into the memory of every Gundam fan. His Dom brought its massive fist down on Lieutenant Matilda Ajan’s Medea transport, crushing the cockpit and killing her. Matilda’s death was one of Amuro’s most devastating losses, and Ortega bore the full weight of audience hatred for it.

Ortega fell alongside Gaia at Odessa. With Mash gone, the two-man formation was a shadow of the Jet Stream Attack — and against a growing Newtype, shadows weren’t enough.

Lieutenant Mash — The First Star to Fall

The most enigmatic member of the Black Tri-Stars. A one-eyed, heavyset man whose total dialogue across the entire TV series consists of a single word: “Sir!” Yet that silence speaks volumes about Mash’s character — a soldier of absolute, wordless loyalty.

Episode 24, “The Black Tri-Stars” (U.C. 0079, November 6). The team launches a Jet Stream Attack against the Gundam. The first attempt is disrupted when Matilda’s Medea intervenes. On the second pass, Amuro finds the counter — he uses Gaia’s lead Dom as a stepping stone, leaping over the formation from above. Before Mash can draw his weapon, the Gundam’s beam saber cuts his Dom in two.

The first Black Tri-Star to die. Mash’s death unraveled the remaining two, and ultimately led to the team’s complete destruction.

The Jet Stream Attack — Tactics and the “Stepping Stone” Legend

How It Works

Three Doms fly in perfect single-file formation, overlapping so precisely that radar reads them as a single unit. In Minovsky particle conditions where radar is unreliable, hiding two machines behind the leader tricks the enemy into thinking they face a 1-on-1 engagement.

Position	Pilot	Role
Lead	Gaia	Opening strike. Forces the target into evasive action
Second	Mash	Pursuit. Strikes the evading target immediately
Rear	Ortega	Finisher. Delivers the killing blow to a trapped target

Originally a tactic used against battleships at Loum — where the targets were huge and couldn’t dodge. Against a mobile suit, the formation’s rigidity became its weakness, and Amuro’s “stepping stone” shattered it.

Amuro’s Counter

As Gaia’s lead Dom charges, the Gundam leaps onto its head as a stepping stone, vaulting over the entire formation. From above — the formation’s blind spot — Amuro strikes directly at the exposed second machine.

This “stepping stone” moment has been parodied and referenced across countless anime and games ever since.

The “Who Are You?” Meme

Gaia’s rallying cry — “Gaia! Ortega! Mash! Jet Stream Attack!” — has a logical problem that Japanese fans have gleefully pointed out for decades. If Gaia is calling out three names and then saying “let’s go,” he’s addressing three people — meaning a mysterious fourth person is giving the order. The inevitable response from internet comments: “Who are you?” It’s one of Gundam’s oldest and most enduring memes.

“Three Minutes” — The Conscon Shock (Episode 33)

The Setup

White Base has just left the neutral space around Side 6. Rear Admiral Conscon’s mobile fleet lies in ambush with 12 Rick Doms — an overwhelming force against one damaged battleship. Conscon, a former aide to Dozle Zabi who considers Char beneath him, expects a guaranteed victory.

Amuro’s Awakening

But the Amuro in the Gundam’s cockpit is no longer the same boy. This battle introduces the first Newtype visual effect — an inexplicable light that flashes across Amuro’s eyes. He perceives enemy movements before they happen. He knows when to fire.

Amuro counts as he shoots: “One… two…” One Rick Dom after another falls. Amuro alone destroys nine. The remaining three are dispatched by Sleggar Law, Sayla Mass, and Kai Shiden — one each.

All 12 Rick Doms. Wiped out in under three minutes.

Conscon’s Scream

“A-Annihilated?! All 12 Rick Doms annihilated?! In… in less than three minutes?! 12 Rick Doms against one damaged battleship! Is it… is it a monster?!”

Conscon’s line became one of the most quoted “losing lines” in all of Gundam. And this scene simultaneously cemented the Rick Dom’s reputation as cannon fodder and served as the definitive proof that Amuro had transcended the limits of ordinary human combat.

Variant Lineage

Model	Name	Series	Description
MS-09R-2	Rick Dom II	0080 / 0083	Unified Maintenance Plan upgrade
MS-09F/trop	Dom Tropen	0083	Desert/tropical specialist
MS-09G	Dwadge	ZZ / UC	Final ground-type mass production model
AMX-009	Dreissen	ZZ / UC	Ultimate Dom evolution by Neo Zeon
MS-09R (TB)	Rick Dom (Thunderbolt)	Thunderbolt	Sub-arms and extra propellant tanks

Rick Dom II (MS-09R-2) — Standardized for Every Pilot

The product of Zeon’s Unified Maintenance Plan, which standardized parts and controls across all MS types. The Rick Dom’s quirky handling characteristics were smoothed out, making it accessible to average pilots. The most famous Rick Dom IIs belong to the Cyclops Team in 0080: War in the Pocket.

Dom Tropen (MS-09F/trop) — The Desert Bull

The tropical/desert specialist from 0083. “Tropen” is German for “tropical.” The iconic image of this machine charging across sand dunes with a Raketen Bazooka slung over its shoulder is one of 0083’s defining visuals, piloted by Delaz Fleet remnants.

Dreissen (AMX-009) — The Final Evolution

Neo Zeon’s ultimate Dom-lineage MS, built using Rick Dom II combat data. Its power output of 2,380kW is nearly double the original Dom’s. Armed with beam lancers and triple arm-mounted beam cannons, the Dreissen eliminated the Dom’s historical weakness in ranged combat.

The Dreissen served in both the ZZ era and the Laplace Incident of U.C. 0096 (Gundam UC), piloted by the “Sleeves” — proving that the Dom’s design philosophy remained viable for over a decade.

The GQuuuuuuX Rick Dom — Tripod Transformation and Fallen Heroes

Tripod High-Mobility Mode — The Dom’s Latest Evolution

The GQuuuuuuX Rick Dom’s greatest innovation: transformation to high-mobility mode without any parts swapping.

Aspect	Normal Mode	Tripod High-Mobility Mode
Form	Humanoid MS	Tripod (rear booster leg deployed)
Mobility	Standard	Devastating acceleration
How	—	Third leg deploys from backpack

A third leg folded into the backpack deploys to create a tripod configuration where all three limbs share nearly identical geometry. Thrust-vectoring nozzles distributed across each foot sole enable propellant-free hover travel.

The design philosophy of “not clinging to pure humanoid form” is the legitimate evolution of the original Dom’s revolutionary choice to abandon walking for hover.

Gaia & Ortega’s Rick Dom — What Happened to the “Heroes of Loum”

The Black Tri-Stars’ fate in GQuuuuuuX (U.C. 0085) is shocking.

Mash — Retired from the military and became a politician. He’s now the mayor of Usen City — and embroiled in an affair scandal with his attractive secretary. The “Hero of Loum” drowning in political scandal is GQuuuuuuX’s black humor at its finest.

Gaia & Ortega — Forced out by M’Quve, they now run a junk shop on Side 6, entering Clan Battles (underground MS fighting tournaments) to make ends meet. Registered in the clan “BINARYS” under codenames “GGG” (Gaia) and “OOO” (Ortega).

The Rick Dom’s high performance backfires — maintenance and ammunition costs are so crushing they’re considering career changes. Gaia’s unit carries only a single Heat Saber (can’t afford full loadout), and Ortega’s machine doesn’t even have that.

With Mash gone, they attempt an incomplete Jet Stream Attack with only two machines. The killing technique that once sank a Federation flagship, performed undermanned and impoverished — a scene that blends genuine pathos with dark comedy, and one of GQuuuuuuX’s finest moments.

Challia’s Rick Dom — The Blue Hunter

Field	Detail
Pilot	Challia Bull (Major → Colonel)
Colors	Blue color scheme
Nicknames	“The Man Who Returned from Jupiter,” “Gray Ghost”

Challia Bull is one of Zeon’s most powerful Newtype pilots, who co-developed the M.A.V. tactical doctrine alongside Char Aznable. M.A.V. is a two-machine cooperative tactic: in Minovsky particle conditions, one unit attacks (revealing its position) while the partner covers or pursues — by U.C. 0085, the term has entered common slang as shorthand for “an inseparable duo.”

Challia’s blue Rick Dom shares the tripod transformation mechanism with Gaia/Ortega’s units, but his overwhelming pilot skill makes it perform on an entirely different level.

Design History

Designer: Kunio Okawara

The Dom was designed by Kunio Okawara, the father of Gundam’s mechanical design. Director Yoshiyuki Tomino gave relatively free rein for enemy MS designs beyond requiring a mono-eye sensor, though for later-series machines like the Dom, Tomino provided rough sketches that Okawara refined into finished designs.

At the time, enemy robots weren’t expected to be merchandised, freeing them from sponsor constraints. The result was a design that felt like a real military weapon. When the Dom was eventually made into plastic model kits, this “realistic military hardware” aesthetic became explosively popular — an unintended benefit of having no commercial restrictions.

The “Fortress” Silhouette — Head Buried in Chest

The Dom’s most distinctive design element is its head sunk into the chest, creating a low-profile stance. Where Zakus and Goufs extend the “humanoid” template, the Dom lowers its head to reduce its target profile while simultaneously lowering the center of gravity for hover stability.

This “neckless” silhouette became the defining visual identity of the entire Dom lineage — inherited by the Dreissen, Dwadge, and every subsequent descendant.

Zimmad vs Zeonic — The Arms Manufacturer Rivalry

Behind the Dom lies a fierce competition between Zeon’s two major MS developers.

Competition	Zimmad	Zeonic	Result
Round 1: MS Dawn	Zudah (EMS-04)	Prototype Zaku	Zudah had fatal flaw → Zeonic wins
Round 2: Mid-War	Dom (MS-09)	—	Zimmad’s triumph. Mass production approved
Round 3: Next-Gen	Gyan (YMS-15)	Gelgoog (MS-14)	Gelgoog’s versatility wins → Zeonic wins

Zimmad learned from the Zudah’s failure and struck back with the Dom — but lost the next-generation race when the Gyan proved too specialized for close combat. Zeonic claimed the last mass-production MS contract. After the war, Zimmad was absorbed into Anaheim Electronics as the “AE/ZIM” division.

Cultural Impact

“Jet Stream Attack” — A Phrase That Transcended Gundam

“Jet Stream Attack” has become so embedded in Japanese pop culture that people who’ve never watched Gundam know the term. Any time three people do anything in sequence, someone will shout “Jet Stream Attack!” Parodies span from Aura Battler Dunbine to Girls und Panzer to Full Metal Panic! — the references are uncountable.

And the “Who are you?” meme (see above) remains one of Gundam’s oldest surviving internet jokes.

“Three Minutes” — The Universal Shorthand for Domination

“All 12 Rick Doms wiped out?! In less than three minutes?!” — Conscon’s scream has become a universal metaphor for overwhelming superiority in Japan. From IT industry commentary (“Our servers went down in three minutes — Conscon would understand”) to sports commentary, the phrase is everywhere.

For the Rick Dom, it’s an infamous legacy as the ultimate “jobber.” But seen another way, the Rick Dom performed the most important job in Gundam: it proved just how far beyond human limits Amuro had evolved. Without “12 machines in 3 minutes,” the scale of Newtype power would remain abstract. The Rick Dom made it concrete.

The Hover MS Concept

The Dom established the concept of the “hovering heavy armored MS” — an idea that influenced not just its direct descendants but the entire Gundam franchise. SEED’s BuCUE, 00’s Tieren Ground Type, and countless others that achieve high-speed ground mobility all carry the Dom’s DNA.
